WHERE DID All MY ITUNES MUSIC GO?

I was listening to music in the car, it was hooked onto an aux cord and the music randomly stopped playing, so I went into my iTunes library and everything is gone. All my playlists, all my songs, and I'm still signed in and everything. I didn't even do anything that would cause this to happen. I had a lot of songs and I'm really confused why the hell they just all decided to disappear? If it helps, I have the iPhone 6s and its iOS 9.2.

Long time paaaasssing! Where did all my iTunes go-oo, long tiiiime ago.

I lost all my music on my iPhone se why?

  • Why did iTunes delete all my apps? I plugged my iPhone into the computer to download a song that I had bought. All I did was upload the song to my phone, press eject, and take it out. When I went back to my home screen, all my apps were gone except 5 of them! Why did this happen!
  • Where did my itunes music go? For some reason all my music in my itunes library deleted, so when I reopened it, it prompted me to set itunes as the default music player. However, it doesn't have any of the old playlists I sync with my iphone… How do I get it back to normal? Apple is *** useless
  • Two songs will not transfer from my computer onto itunes like all the others did? Okay, so I checked google and it was no help. I recently upgraded from my optimus smartphone, to an Iphone 4. Now I was able to get all my music onto my computer from the old SD card, and then I was able to transfer the songs onto itunes, then onto my phone. Then i found out that two songs, two i love the most mind you, will not transfer, I drag them over like i did with the others but they won't appear in itunes, why?
  • If you've ever been cheated on, how did you feel and what did you do? I've never caught a partner cheating on me yet, but I think if I did I would have to cause them a lot of problems. What did you do about a cheating partner?
